vgcfgrestore

Hello,

Looks like I am going to have to resort to using vgcfgrestore as I get the following error running vgscan:

vgscan -- removing "/etc/lvmtab" and "/etc/lvmtab.d"
vgscan -- reading all physical volumes (this may take a while...) vgscan -- scanning for all active volume group(s) first vgscan -- found active volume group "data_vg"
vgscan -- reading data of volume group "data_vg" from physical volume(s)

vgscan -- ERROR -364: can't get data of volume group "data_vg" from physical volume(s)
vgscan -- ERROR -364 creating "/etc/lvmtab" and "/etc/lvmtab.d"

I assume with an error like that there is no way I am going to be able to activate my logical volumes on the next reboot?

Also I haven't seen anywhere where it says that the logical volumes and volume group must be offline when running vgcfgrestore other than this piece at the end of the vgcfgrestore man page:

vgcfgrestore returns an exit state of 0 for success and > 0 for error:

       1  no physical volume on command line
       2  invalid physical volume name
       3  volume grou is active
        ......

So I will ask the question. Can vgcfgrestore be run on active logical volumes and volume groups?

I will answer my own questions just in case somebody is searching through the archives for answers to similar problems.

As I thought the volume group did have to be inactive. One note though. I could not successfully run vgcfgrestore in single user mode. I kept getting an error (which I didn't write down) until I went to run level 3 without
activating my volume group. Good news is that the restore worked and vgscan now runs properly.

Correction to this piece. :-)

On reboot the logical volumes did come up properly (I removed vgscan from the startup scripts) which suprised me.
